LAUNDRY-DRIER.

SPECIFICATION forming part of Letters Patent No. 336.758, dated February 23, 1886.

To aZZ whom it may concern: air within said drying-chamber; and F F are Be it known that I, OscAR M. SHANNON, a the nues or passages by which the airis withresident of Chicago, in the county of Cook and drawn from the drying-chamber after it has State of Illinois, have invented certain new passed upward through the clothes and taken and useful Improvements in Laundry-Driers; up its quota of moisture therefrom. 55

and I do hereby declare that the following is It is a distinctive feature of the present ina full, clear, and exact description thereof, vention that the outlet-iluesFare constructed reference being had to the accompanying drawto deliver at some point in the passage which ings, and to the letters of reference marked conducts away the products of combustion 1o thereon, which form a part of this speciiicafrom the stove, thereby utilizing the chimney- 6o tion. flue and insuring an active circulation of air This invention relates to that class of launthrough the drier. drydriersin which the drying-chamberis pro- The stove B, as it is shown inl the present vided with a series of sliding gates adapted to drawings, consists of a fire-box, B', a surbe separately drawn out of the chamber for rounding water-back,b,and an ash-pit,b.

In the operation of the drier having its circulating-flues constructed as above set forth, the air from the drying-chamber enters the current of combustion products,and the draft of the stove impels a movement of such air, which is far more active and efficient than it is vwhen said air is discharged by an independent outlet.

For the general object last-above mentioned it would be practicable to connect the air-outlet flues F with the chimney direct or with the pipe D; but as there is sometimes a temporary back draft in the chimney and the pipe D', resulting from change in the direc-- tion'of the wind or other cause, there is danger that soot will be blown into the dryingchamber through the fines F with the effect of soiling the clothes. I therefore prefer to conneet the said flues F with the passage for the combustion products at the point indicatedto wit, between the heating-drum and the iire box-or at a point of the heating-drum itself, for the reason that within said drum the movement of the current is slow, and the soot thus returned will naturally be deposited.

Referring next to the sliding gates,one of my V improvements therein consists in providingr for each gate a pulley, C', or its equivalent support located at a little distance in front of the drier-wall through which the gates are drawn out, which pulley, acting in conjunction with inner guide-pulleys, sustains the gate in a substantially horizontal position when drawn out, thereby dispensing with the long stationary rails which have heretofore been employed to sustain the extended gate and .lessening the space occu pied by the apparatus.

Another improvement relating to the gates consists in providing a metal rail, C2, at the top of each gate to run on the stationary pulley or support, C', substantially as shown.

The gates C are composed of the end uprights, c c2, united by the horizontal bars c, said uprights being Wide enough to close the opening provided in the wall A for the passage ofthe gate and the articles thereon when the gate is either entirely closed or entirely drawn out.

C3 G3 are stationary rails or bars, which in my improved construction are limited to the interior of the drier, and are each employed only to uphold and guide the inner end ofa gate through the medium of the pulleys c3 c4 set in the mortise of the inner upright, c?.

The elevated metal rail C2 is attached to 'the uprights c c2, and at its front end is extended beyond the upright c far enough to reach over the pulley C when the gate is closed. By this construction the said rail resting on the pulley C co-operates with the lowermost pulley c3 to hold the gate horizontal in its ex tended position.

As a desirable construction, a series of loose pulleys, C', may be mounted on a rod, c5, the rod being supported at its ends by brackets C'4 and upheld between its ends by hangers or pendent straps G6, as shown in Figs. 2 and 3.

The extent to which the brackets C4 project in front of the adjacent wall of the drier-chamber will of course be sufficient to give the desired horizontal distance between the bearing points c3 and C', to hold the gate practically horizontal when fully drawn out.

I claim as my invention- 1. In combination with a drying chamber provided with inlet and outlet air passages and a heating-drum, a heater constructed with a passage leading from the fire-space to the heating-drum, and a passage connected with the air-outlet and leading into the said passage to the drum, substantially as described.

2. The combination, with a drying-chamber provided with an air-outlet, of a heatingdrum located within said chamber, and a broad air-distributing box connected with a suitable air-inlet and located below the heating-drum, and also provided withV widely distributed holes in its upper inclosing-wall, whereby the air is delivered in relatively -small streams beneath various and widely-distributed porn tions of the heating-drum, substantially as described.

3. The combination, with the drying-chamber, of an air-outlet passage terminating at its receiving end in a horizontal passage, F, having several openings at different parts of the drying-chamber, substantially as and for the purpose set forth.

4. The combination, with a drying-chamber provided with a heatingdrum and an airoutlet pipe, of a heater provided with a passage, b, leading to the heatingdrum, and a passage, B3, connected with the air-outlet of the drier and opening vinto the passage b3, and also provided with a damper, b", substantially as and for the purpose set forth.

5. A sliding drier-gate provided with a rail extended beyond the front end of the gate, in combination with a stationary pulley supported in front of the drier, and a supportarranged within the drier to receive upward pressure from the inner end of the gate, substantially as described.

6. In combination with the dryingchamber having a xed interior rail and an external pulley, C', supported in front of the drier, a sliding gate provided with pulleys c3 c,run ning on said inner rail, and an elevated rail, G2, running on the exterior pulley, substantially as described.
